Manufacturing in the euro zone slowed slightly in June.
The growth rate was the weakest in four months and Markit’s survey of purchasing managers at 3,000 firms suggested output may have peaked in April.
Frailty was most notable in Spain, which offset still-strong output growth from Europe’s largest economy Germany.
UK manufacturing output appeared in slightly better health than the rest of Europe, although it too slowed from a May’s 15-year high.
And there were signs of cooling in China’s economy.
Stock markets and commodity prices fell in Asia after a major survey of Chinese purchasing managers added to concerns over the global outlook.
HSBC’s China Purchasing Managers’ Index fell to a 14-month low with both output and new orders dropping outright for the first time since the depths of the economic downturn in March 2009.
